India Residential Energy Storage Market

Overview

The India residential energy storage market was valued at USD 74.0 million in 2025 and is projected to reach USD 388.4 million by 2032, expanding at a CAGR of 27.0% from 2026 to 2032. India's residential energy storage sector is entering a phase of structural transformation, underpinned by the government's ambitious renewable energy targets, persistent grid reliability challenges in rural and semi-urban regions, and the rapid proliferation of rooftop solar installations across the country's 303 million households. The Ministry of New and Renewable Energy (MNRE) has set a national target of 500 GW of renewable energy installed capacity by 2030, of which rooftop solar alone is targeted at 40 GW under the PM Surya Ghar Muft Bijli Yojana, announced in February 2024 with a budgetary outlay of INR 75,021 crore (approximately USD 9.0 billion). This scheme, targeting one crore (10 million) households with subsidized rooftop solar and storage installations by 2027, represents the single largest government-backed demand catalyst for the residential energy storage market in India's history. Each solar-integrated storage installation under the scheme is estimated to generate average battery storage demand of 5 to 10 kWh per household, implying a total addressable storage market of 50 to 100 GWh under the programme alone.

 

India's residential electricity landscape is characterized by significant supply-side volatility, with 15 to 22% of the country's rural population still facing daily power outages of 4 to 12 hours according to the National Sample Survey 2023. The Central Electricity Authority (CEA) estimates that approximately 31 million rural households continue to experience unreliable grid connectivity, making battery-based home energy storage a functional necessity rather than a discretionary technology investment. Battery prices for lithium-ion chemistries, which dominate the residential storage technology landscape, have declined 89% over the past decade according to BloombergNEF, falling to approximately USD 139 per kWh in 2023 and projected to reach below USD 80 per kWh by 2030, significantly improving residential storage economics.
